PLM system: leading system for Material Master, Bill of Material, and related documents.
The PLM System is the leading system for product definition data, meaning bill of material and at least all active documents related to these items. ("Active" means all documents where the intellectual property is owned by the organization.) All Engineering Changes regarding product definition are executed in the PLM system. If a change during the serial production is initiated in SAP, then the Change Request is moved to the PLM system, executed there and after finalization all changed items are moved to SAP again.
